Régénération naturelle à faible coût dans le cadre de l’aménagement forestier en zones tropicales sèches en Afrique (Natural generation at low cost as part of forest management in African tropical dry landscapes)

The author examines effective, low-cost, and often-overlooked methods of natural regeneration by root suckering and terrestrial layering in African tropical dry forests. He suggests this method of regeneration for both inside and outside of forested areas.

Afforestation for Reclaiming Degraded Village Common Land: A Case Study

background

In India, population growth and agriculture put a strain on natural resources, often resulting in "wastelands" where the soil is no longer productive - often either affected by either salt or alkilinity. Using soil amendments to restore these lands to productivity can be cost-prohibitive for the small villages that own these lands. Afforestation is one possible method for restoring the health of these in a cost-effective and scalable way.

Semeando Sustentabilidade em Apuí (Seedling Sustainability in Apuí)

The project aims to strengthen environmental management in Apuí, and to increase capacity for the development of more sustainable productive activities. To achieve this goal the project works simultaneously on reinforcing the network of seeds and seedling production, strengthening institutions, supporting planting and forest conservation, building capacity of landholders in rural properties, and providing environmental education and assistance for the creation of a development plan for the municipality. By means of the rotational management of pastures, the project predicts that it will be possible to identify the best alternative to increase production and profitability while simultaneously halting the advancement of deforestation.

The Role of Revegetation for Rehabilitation of Sodic soils in Semiarid Subtropical Forest, India

background

This study relies on a  case study evaluate the rehabilitation of barren land within a larger forest ecosystem. The article indicates that restoration opportunities exist even with severely degraded land where natural succession does not occur without management practices.

Effect of Adult Density on Regeneration Success of Woody Plants in Natural and Restored Tropical Dry Evergreen Forest Fragments in Puducherry Region, India

Background

This study tested variables contributing to successful regeneration of Tropical Dry Evergreen Forest (TDEF) species in southern India, a forest type that is highly biodiverse but fragmented and commonly designated as “sacred groves”.

Conclusions & Takeaways

The researchers found that whether in longstanding “groves” or in reforested areas, adult tree density more strongly enhances the regeneration of any given species than do other factors such as the species’ dispersal mode or life form (e.g. tree, shrub, or liana).

Bwa Yo: Important Trees of Haiti

background

This book, published in 1996, presents important tree species in Haiti as part of a USAID effort to address environmental degradation in Haiti. The trees presented are mainly those in the agricultural landscape, providing food or fuel, although trees with cultural or ecological importance are also presented.

Each tree profile provides information and photos including discussions of the species and common names, importance, taxonomy and botanical features, distribution and ecology, tree characteristics, utilization, propagation, and other findings (biomass studies, growth performance, tree improvement, seed research, and/or planting stock quality).

Experiments on Ecological Restoration of Coal Mine Spoil using Native Trees in a Dry Tropical Environment, India: A Synthesis

background

This article outlines a series of experiments on the growth performance of 17 native tree species, as well the suitability of select species for use in plantations and to restore soil fertility on an abandoned coal mine in India. All 17 species grew in degraded mine soil, with A. catechu, B. racemosa, D. strictus, L. coromandelica and T. arjuna showing the highest biomass accumulation in mine soil; certain species showed higher biomass accumulation in mine soil fertilized with full or half doses of NPK.

Restoration of degraded forest land in Thailand: the case of Khao Kho

Background

This chapter discusses the deforestation of Khao Kho district, situated in Thailand’s central highlands, in the 1970s and restoration efforts in the 1990s. Over 75% of the district was forested until 1968, when as a counterinsurgency strategy the Royal Thai Army began to build roads, deforest the district and encourage agricultural settlement in this heretofore intact forest. Deforestation and maize cultivation on these steep hillsides, often with already-poor soil quality degraded in situ, led to rapid degradation with farming untenable by 1990. A UNDP-funded reforestation project – managed by the Army – was initiated in 1990.
